NGC 3603-A1 is a pair of giant stars locked in a rapid 3.8-day orbit. Their dynamic relationship provides clues to how ...

Stars are the fundamental building blocks of our universe. Most stars host planets, like our Sun hosts our solar system, and if you look more broadly, groups of stars make up huge structures such as ...

Astronomers have developed the most realistic model to date of planet formation in binary star systems. The researchers, from the University of Cambridge and the Max Planck Institute for ...

Binary (or double) stars may in fact hinder life as we know it, new observations by the Atacama Large Millimeter/submillimeter Array (ALMA) in northern Chile, reveal. Details of the millimeter ...

Planets can orbit one star in a binary system (S-type orbit). Planets can orbit both stars in a binary system (P-type orbit). Planets might share an orbit with a smaller star in a binary system ...

Could our sun have had a partner star during the early days of the solar system? A new study suggests our sun may have had a binary companion, like the system of the planet Tatooine from the original ...
